The Group's power generation of thermal power generation units decreased by approximately 2.73% when compared to the corresponding period of the previous year which was attributable to a slowdown in economic growth of China and the decrease in overall regional on-grid utilisation hours of thermal power generation units and the impact brought by planned maintenance of generation units. The Group's power generation of hydro-electric power generation units decreased by approximately 5.35% when compared to the corresponding period of the previous year as a result of the decrease in inflow water in the basin where the generation units situated. Since the capacity of the Group's wind power generation units increased on a year-to-year basis and as a result of elevation of efficiency, power generation of the Group's wind power generation units increased by approximately 53.42% when compared to the corresponding period of the previous year.
